Abstract

Abstract

The impact of soil conditioning is a critical factor influencing shield tunneling efficiency in strata of gravelly sand. Through a slump test, the impacts of foam, bentonite slurry, and polymer on the enhanced soil’s flow plasticity were examined. A prediction model of soil slump was provided using machine learning techniques like SVR, KNR, RFR, and BPNN, utilizing the test results as the data sample set. The predicted and real values were then compared and examined. The study indicates that: (1) Foam has a greater impact on enhancing the gravelly sandy soil’s flow flexibility. (2) High-viscosity bentonite slurry or PAM solution should be applied over gravelly sandy stratum with high water content to retain water, improve viscosity, and prevent blowout. (3) The RFR model outperforms the SVR, KNR, and BPNN models regarding prediction accuracy. It can also forecast the slump of the improved waste soil with greater precision. The model’s interpretability was examined as well.
